Dad had a rough night last night. When I visited him after work, his oxygen levels were lower (mid 80s) than the doctors wanted so they adjusted his ventilator to give him slightly larger breaths of the pure oxygen he was already breathing. At the same time, his heart rate was fast and irregular. It varied between 140 and 180 beats per minute. After performing an EGK, they gave him some medication for the heart rate and did another adjustment to the ventilator and by this morning his heart rate was down to 110 and his oxygen levels were up to 93%.
Overall this seems like two steps backward and then one forward.
We are working on setting up a meeting with Dad's doctors to evaluate how is doing and where we need to go from here to meet Dad's wishes.
